Lignin gasification in supercritical water over charcoal supported ruthenium trivalent salts was studied using a batch reactor at 673 K. Ruthenium (III) nitrosyl nitrate on charcoal (Ru(NO)(NO 3 ) 3 /C) was more active than ruthenium (III) chloride on charcoal (RuCl 3 /C) for the gasification reacti...
